IMPROVEMENT IN GRAIN-DRILLS.

Specification forming part of LettersPatent No. 186,407, dated January 23, 1877; application filed November 8, 1876. i

To all whom it may concern:

Be it known that I, JOHN G. BAKER, of Mechanicsburg, in the county of Ohampaign and State of Ohio, have invented certain new and useful Improvements in Grain -Drills; and

I do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being had to the accompanying drawing,

which form part of this specification.

My invention relates to grain-drills; and

consists in the peculiar combination of parts,

whereby pressure is applied to the drag-bars,

as hereinafter more fully set forth and claimed. In the drawing, representing a perspective view of a grain-drill embodying my invention,

A represents the frame, constructed of common gas-pipes or hollow tubes of iron, which renders the same very light, durable, and strong, and also simplifies its construction,

the tubes or pipesbeing joined at the angles in the same manner as is commonly employed in fitting gas-pipes.

As strength, lightness, and durability are desirable qualities in a grain-drill, it is obvious that the above-described c'onstruction possesses great advantages over all known methods of construction.

B represents the axle, to which the frame is secured. O are the drag-bars, pivoted to the front of the frame, and attached to the hoes D of the drill. E is the springcarrying bar, pivoted to the sides of the frame. It. i 'has rigidly attached to it the arm G, and also the springs E. On the axle is placed the sleeve I, to which is rigidly secured the bellcrank lever K, to the lower arm of which is fastened the connecting rod or pitman L, the

other end of which attaches to the arm G of the spring-bar E. M is the lifting-bar, bent as shown in the drawing, the ends of which are pivoted to the sides of the frame. It is provided with the handle m, by which it is elevated or lowered. To said lifting-bar are attached, by chains or other'suitable means, the hoes D, which are placed in and out of operative position by raising or lowering said bar.

The manner of applying pressure to the drag-bars is as follows: By depressing the liftingbar M, so that the hoes are lowered to operative position, it operates on the upper ment to 'be very useful, in fact indispensable,

for the purpose devised. v

When the lifting-bar M is raised, elevating the hoes, the drag-bars will press against the springs, which will readily yield to the pressure by reason of the removal of the liftingbar from the arm of the bell-crank lever.

What I claimv as my invention, and desire to secure by Letters Patent, is-

l. The combination, with the main frame of a grain-drill,-pivoted so as to be adjusta-' ble in a vertical plane, of spring-pressed hoes, the latter operated by the rear bell-crank lever; intermediate connecting-link, and rear presser-bar, substantially as described.

2. In a grain-drill, the combination of dragbars 0 and spring-bar E, provided with springs H and arm Gr, with the pitman L,bell-crank lever K, and lifting-bar M, substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

. JOHN G. BAKER.
